The federals have a program called a program called "Vigilant Eagle" part of Homeland Security to watch and report any anti-Obama or U.S. Government posts on social media.
From The Rutherford Institute:
In the four years since the start of Operation Vigilant Eagle, the government has steadily ramped up its campaign to “silence” dissidents, especially those with military backgrounds. Coupled with the DHS’ dual reports on Rightwing and Leftwing “Extremism,” which broadly define extremists as individuals and groups “that are mainly antigovernment, rejecting federal authority in favor of state or local authority, or rejecting government authority entirely,” these tactics have boded ill for anyone seen as opposing the government.
One particularly troubling mental health label being applied to veterans and others who challenge the status quo is “oppositional defiance disorder” (ODD). As journalist Anthony Martin explains, an ODD diagnosis
“denotes that the person exhibits ‘symptoms’ such as the questioning of authority, the refusal to follow directions, stubbornness, the unwillingness to go along with the crowd, and the practice of disobeying or ignoring orders. Persons may also receive such a label if they are considered free thinkers, nonconformists, or individuals who are suspicious of large, centralized government… At one time the accepted protocol among mental health professionals was to reserve the diagnosis of oppositional defiance disorder for children or adolescents who exhibited uncontrollable defiance toward their parents and teachers.”
The case of 26-year-old decorated Marine Brandon Raub—who was targeted because of his Facebook posts, interrogated by government agents about his views on government corruption, arrested with no warning, labeled mentally ill for subscribing to so-called “conspiratorial” views about the government, detained against his will in a psych ward for standing by his views, and isolated from his family, friends and attorneys—is a prime example of the government’s war on veterans.

Raub’s case exposes the seedy underbelly of a governmental system that is targeting Americans—especially military veterans—for expressing their discontent over America’s rapid transition to a police state.
